Key Parameters

Substitute Part Grouping Explanation

Substitution of the LT1396CS8#TRPBF is determined by compatibility across the following critical parameters:

Mandatory Compatibility Criteria:

• Amplifier Type: Current Feedback topology
• Number of Circuits: 2 channels
• Package / Case: 8-SOIC form factor (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Voltage Supply Range: Overlap within 4V to 12V span

Performance Parameters Affecting Substitution:

• Slew Rate (800V/µs baseline)
• -3dB Bandwidth (400 MHz baseline)
• Current - Input Bias (10 µA baseline)
• Voltage - Input Offset (1 mV baseline)
• Current - Supply per channel (4.6 mA baseline)
• Current - Output per channel (80 mA baseline)

Substitute parts must maintain the 8-SOIC package geometry and dual-channel current feedback architecture. Variations in performance parameters are acceptable when the substitute part meets or exceeds the baseline specifications or when application requirements permit reduced performance in specific parameters.

Parameter Comparison

Engineering Selection Recommendations

LMH6724MA/NOPB and LMH6724MAX/NOPB (National Semiconductor)

These dual-channel current feedback amplifiers are direct functional substitutes for the LT1396CS8#TRPBF. Both parts maintain the 8-SOIC package geometry and dual-channel architecture. The LMH6724 series exhibits lower supply current consumption (1 mA per channel versus 4.6 mA) and higher output current capability (110 mA per channel versus 80 mA). Slew rate is reduced to 600V/µs and bandwidth to 370 MHz. Both parts are active products with extended operating temperature ranges (-40°C to 85°C). The LMH6724MA/NOPB is supplied in bulk packaging, while the LMH6724MAX/NOPB is also bulk packaged. Both are ECCN EAR99 classified and suitable for applications where lower power consumption is advantageous.

OPA2674ID (Texas Instruments)

The OPA2674ID is a dual-channel current feedback amplifier in 8-SOIC packaging with significantly enhanced performance characteristics. This part delivers 2000V/µs slew rate and 500 mA output current per channel, substantially exceeding the LT1396CS8#TRPBF baseline. However, supply current consumption is elevated at 18 mA per channel, and the -3dB bandwidth is reduced to 260 MHz. The OPA2674ID is ROHS3 compliant with MSL rating of 2 (1 Year). This substitute is appropriate for applications requiring maximum output current and slew rate performance.

OPA2683ID (Texas Instruments)

The OPA2683ID is a dual-channel current feedback amplifier with differential output configuration in 8-SOIC packaging. This part features 540V/µs slew rate, 150 mA output current per channel, and minimal supply current of 1.88 mA per channel. Input bias current is 3 µA and input offset voltage is 1.5 mV. The OPA2683ID is ROHS3 compliant with MSL rating of 2 (1 Year). The differential output topology distinguishes this part from the LT1396CS8#TRPBF and may require circuit design modifications. This substitute is suitable for applications requiring low power consumption and differential signal processing.

All substitute parts are active products with ECCN EAR99 classification and REACH Unaffected status, matching the regulatory compliance profile of the main part.

Frequently Asked Questions (FAQ)

Q: Can the LMH6724MA/NOPB directly replace the LT1396CS8#TRPBF without PCB modifications?

A: Yes. Both parts are housed in 8-SOIC packages with identical pin pitch (0.154", 3.90mm width) and dual-channel current feedback architecture. Pin-for-pin compatibility is maintained. However, the reduced slew rate (600V/µs versus 800V/µs) and bandwidth (370 MHz versus 400 MHz) must be verified against application requirements.

Q: What is the primary advantage of the OPA2674ID substitute?

A: The OPA2674ID provides maximum output current capability at 500 mA per channel and exceptional slew rate at 2000V/µs. These characteristics are beneficial for applications requiring high-current output stages or extremely fast signal transitions. The trade-off is increased supply current consumption at 18 mA per channel.

Q: Is the OPA2683ID suitable as a direct replacement for the LT1396CS8#TRPBF?

A: The OPA2683ID maintains 8-SOIC package compatibility and dual-channel current feedback topology. However, the differential output configuration differs from the LT1396CS8#TRPBF single-ended output. Circuit design modifications are required to accommodate differential output signal processing. Verify application compatibility before selection.

Q: Which substitute part offers the lowest power consumption?

A: Both the LMH6724MA/NOPB and LMH6724MAX/NOPB deliver 1 mA supply current per channel, and the OPA2683ID operates at 1.88 mA per channel. These represent significant reductions compared to the LT1396CS8#TRPBF at 4.6 mA per channel. The LMH6724 series is optimal for power-constrained applications.

Q: Are all substitute parts ROHS3 compliant?

A: The OPA2674ID and OPA2683ID are explicitly ROHS3 compliant. The LMH6724MA/NOPB and LMH6724MAX/NOPB do not specify RoHS status in the provided data. Verify RoHS compliance requirements with the supplier or manufacturer for National Semiconductor parts.

Q: What is the operating temperature range difference between the main part and substitutes?

A: The LT1396CS8#TRPBF operates from 0°C to 70°C. All substitute parts (LMH6724MA/NOPB, LMH6724MAX/NOPB, OPA2674ID, and OPA2683ID) operate from -40°C to 85°C, providing extended temperature range capability suitable for industrial and automotive applications.

Q: Can I use the OPA2674ID in a space-constrained design?

A: Yes. The OPA2674ID maintains the 8-SOIC package form factor (0.154", 3.90mm width) identical to the LT1396CS8#TRPBF. Package dimensions are not a limiting factor. However, thermal management may require consideration due to elevated supply current consumption at 18 mA per channel.

Q: What packaging formats are available for these substitute parts?

A: The LMH6724MA/NOPB and LMH6724MAX/NOPB are supplied in bulk packaging. The OPA2674ID and OPA2683ID are supplied in tube packaging. The LT1396CS8#TRPBF is supplied in tape and reel (TR) format. Verify packaging compatibility with assembly equipment and procurement requirements.
